Music is not that bad, after all.
The story you've told is not my cup of tea, but I wish you be more accurate with clearing and outputting smth to ZX screen, you have here lots tearing which spoils overall impression.

I do not think I was the target audience because it is all about childhood references and those of mine belong to a very different era in a very different place, so I found it hard to connect.
What I liked about this was mainly the tune with its intentionally beeperish sound and some graphics. Weak thumb up from me then.
